    I have an old Tandy 1400FD that has dead batteries. This was the first computer I ever purchased for myself. I think I got it about 1988? It has been sitting in it's bag unused for several years. Both the main 4-cell battery pack and the RTC backup battery are dead. I was able to get some...

    Multiple Motherboards/System Boards

    I'm just curious how some of you folks handle your using multiple system boards. Do you have a customize "case", or build unit, where you swap in the motherboard, power supply, video and sound cards, etc. And then run it until you want to test out another system board? Then you take it apart and...

    Can I leave the battery off on 8088 and 80286 systems?

    I 've watched a few videos where the Varta battery is cut off the motherboard of an 8088 or 80286. As far as I can tell it is okay to leave the battery off. I will just have to enter the date and time when the OS starts up. Is that correct? Can I leave the motherboard without a battery? Seaken

    Hello from upstate NY

    Happy to have found this nice forum. I've read all the stickies and think you've done a very nice job setting this place up. I go back as far as dialing in to BBS systems to learn all I could about CP/M. That was in about 1987. Yes, I came late to the game. I was born in Seattle, WA in 1964 and...
